Description

Technical Field

[0001] The present application relates to the technical field of utility pens, and in particular to a utility pen. Background Art

[0002] With the development of electronic devices, the design of electronic components has become increasingly sophisticated, and assembly has become increasingly difficult. Existing electronic devices typically mount electronic components onto PCBs and then secure them by heating them in a furnace. Therefore, the typical electronic component assembly process involves screen printing (or dispensing), mounting, curing, reflow soldering, cleaning, testing, and finally, repair. During the assembly process, the product must be precisely mounted on the PCB, but no machine can operate with absolute stability. Sometimes, placement machines (also known as chip mounters) can cause flying parts or material offsets. In these cases, the product needs to be repaired.

[0003] The typical repair process involves using tweezers to remove and clean the electronic component, then using another repair tool to move the solder paste together. Finally, using a different tweezers tool, the cleaned component is placed back onto the solder paste, and then placed back into the soldering oven for solidification. This operation is time-consuming, inefficient, and inconvenient, leading to excessive hand fatigue and numerous other uncertainties. If your hands are tired and you're not careful while switching tools, you could damage other components. For example, if you accidentally bump into another component while changing tweezers, those components will need to be repaired again. Summary of the Invention

[0025] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] like Figures 1 to 4As shown, an embodiment of the present application provides a tool pen, including: a rod body, a needle assembly and a locking assembly, the rod body 10 includes a rod body 11 and tweezers 12, and the tweezers 12 are fixedly connected to one end of the rod body 11; the needle assembly 20 includes a needle body 21 and a sliding rod 22, the needle body 21 is fixedly connected to one end of the sliding rod 22, the sliding rod 22 is slidably arranged in the rod body 11, and the other end of the sliding rod 22 can pass through the rod body 11 away from one end of the tweezers 12; the locking assembly 30 and the sliding rod 22 have a first locking state and a second locking state, when the locking assembly 30 and the sliding rod 22 are in the first locking state, the needle body 21 is located inside the tweezers 12, and when the locking assembly 30 and the sliding rod 22 are in the second locking state, the needle body 21 passes through the clamping end 125 of the tweezers 12. Such a setting enables the tool pen to achieve the extension and retraction of the needle body 21 relative to the tweezers 12 by pressing the sliding rod 22, so that the tool pen has two states in which the tweezers 12 and the needle body 21 are used separately. One tool can achieve two maintenance states, avoiding the need to switch the maintenance tool multiple times. At the same time, the locking assembly 30 can ensure that the switching between the two states does not occur during use, avoiding the occurrence of accidental damage to the workpiece. The present application effectively solves the problem in the prior art that the maintenance of electronic components requires multiple switching of the tool tweezers 12 and the needle body 21, resulting in excessive maintenance time and excessive hand fatigue. It should be noted that the integration of the tweezers 12 and the needle body 21 into one body eliminates the need to remove the tweezers 12 or the needle body 21 when switching between the two during use. The conversion of the two can reduce the movement of the tweezers 12 body or the needle body 21 body, and avoids secondary positioning, which can effectively save operation time, thereby reducing the time consumed by the user for changing tools, improving maintenance efficiency, and avoiding the physical energy consumed by unnecessary movements and wrist fatigue.

[0027] like Figure 4 As shown, in the technical solution of this embodiment, the sliding rod 22 includes a sliding block 221 and a sliding rod body 222. The diameter of the sliding block 221 is larger than the diameter of the sliding rod body 222. The rod body 11 is provided with an opening 111. The locking assembly 30 includes a locking member 31. The locking member 31 is rotatably connected to the rod body 11. One end of the locking member 31 can extend into the opening 111 and abut against the sliding rod body 222. The sliding block 221 and the sliding rod body 222 form two steps. When the locking member 31 enters the opening 111 and abuts against the sliding rod body 222, the locking member 31 forms a stop against the aforementioned steps. By restricting the sliding block 221 and the sliding rod body 222, the sliding rod body 222 is locked. Specifically, when the locking member 31 is stopped against the step near the needle body 21, the needle body 21 is in a retracted state. When the locking member 31 is stopped against the step away from the needle body 21, the needle body 21 is in an extended state.

[0028] like Figures 1 to 4As shown, in the technical solution of this embodiment, the rod body 11 is provided with a fixed link 112, and the locking member 31 is rotatably connected to the end of the fixed link 112 away from the rod body 11. The setting of the fixed link 112 is used to fix the rotation axis of the locking member 31. Such a setting ensures the direction of rotation of the locking member 31 and the specific position before and after rotation, thereby ensuring the stability of the locked state. It should be noted that there are a first through hole and a second through hole that match each other between the fixed link 112 and the locking member 31. The connection between the fixed link 112 and the locking member 31 is achieved by the latch 114 passing through the first through hole and the second through hole. That is, the fixed link 112 fixes the latch 114, and the locking member 31 is rotatably connected to the fixed link 112 through the latch 114.

[0029] like Figure 1 、 Figure 2 and Figure 4 As shown, in the technical solution of this embodiment, a first elastic member 113 is provided between the end of the locking member 31 away from the opening 111 and the rod body 11. The first elastic member 113 is fixedly connected to the rod body 11 and applies a thrust to the locking member 31. The first elastic member 113 can continuously apply a thrust to the locking member 31, that is, continuously apply a thrust away from the rod body 10 to the end of the locking member 31 away from the opening 111. This arrangement ensures that the end of the locking member 31 inserted into the opening 111 has a continuous pressure, so that the locking member 31 can push against the sliding rod body 222, thereby ensuring that the position of the sliding rod body 222 is fixed and does not slide.

[0030] like Figure 4 As shown, in the technical solution of this embodiment, the end of the tweezers 12 near the rod body 11 is a cylindrical shell 121, and the outer diameter of the cylindrical shell 121 transitions with the inner diameter of the end of the rod body 11 near the tweezers 12. The cylindrical shell 121 of the tweezers 12 is fixedly connected to the rod body 11 through the transition fit. This arrangement allows the tweezers 12 to be detached from the rod body 11 to adjust tweezers of different lengths and sizes. At the same time, the transition fit also ensures that the two are tightly connected and will not fall off during use. It should be noted that the tweezers 12 include a clamping end 125 and a socket end 126. The clamping end 125 is the clamping end of the tweezers 12, and the socket end 126 is the port for transitional fit with the rod body 11. The outer diameter of the socket end 126 is smaller than the outer diameter of the cylindrical shell 121, so that the socket end 126 can be fully inserted into the rod body 11. In appearance, the cylindrical shell 121 has good consistency with the rod body 11.

[0031] like Figure 4As shown, in the technical solution of this embodiment, the inner diameter of the cylindrical housing 121 gradually decreases along the axis away from the rod body 11. A sleeve 122 is also disposed within the cylindrical housing 121 and fixedly mounted therein. This gradually decreasing inner diameter allows the sleeve 122 to be pushed to the end of the cylindrical housing 121 near the clamping end 125 during installation. When the inner diameter of the cylindrical housing 121 is smaller than the outer diameter of the sleeve 122, this prevents the sleeve 122 from sliding out and also provides a position limit for the sleeve 122. The sleeve 122 is used to accommodate a portion of the needle body 21, preventing it from sliding out and falling. It should be noted that the gradually decreasing inner diameter can form a step on the inner diameter of the cylindrical housing 121. A step that mates with this step can be provided on the end of the sleeve 122 away from the needle body 21. This allows the sleeve 122 to better mate with the inner diameter of the cylindrical housing 121 and provides a better position limit. Another fixing method may be to provide an internal thread in the cylindrical shell 121 and an external thread in the sleeve 122, and to fix the connection through threaded fit.

[0032] like Figure 4 As shown, in the technical solution of this embodiment, a limit block 115 is provided at one end of the inner diameter of the rod body 11 close to the cylindrical shell 121, and the sliding rod body 222 is matched with the inner diameter clearance of the limit block 115. The sliding rod body 222 also includes a fixed limit member 223, and the limit member 223 is located inside the cylindrical shell 121. The matching arrangement of the limit member 223 and the limit block 115 limits the distance that the sliding rod body 222 slides in the direction away from the needle body 21, and the matching arrangement of the sliding block 221 limits the specific displacement range of the sliding rod body 222. It should be noted that the matching of the inner diameter clearance of the sliding rod body 222 and the limit block 115 facilitates the sliding of the sliding rod body 222, and the limit member 223 can be fixedly connected to the sliding rod body 222 by bonding. Such an arrangement can achieve unrestricted assembly of the sliding rod body 222.

[0033] like Figure 4As shown, in the technical solution of this embodiment, the end of the sleeve 122 away from the rod body 11 is provided with a needle hole, and the end of the sleeve 122 closer to the sliding rod body 222 is provided with an elastic body 123. The needle body 21 can pass through the elastic body 123 and the needle hole. The elastic body 123 and the end of the sleeve 122 away from the sliding rod body 222 are provided with a second elastic member 124. The second elastic member 124 applies a thrust to the elastic body 123. The provision of the elastic body 123 is used to transmit the force of the second elastic member 124. At the same time, the provision of the elastic body 123 can prevent the second elastic member 124 from directly applying the elastic force to the sliding rod body 222. It can absorb the elastic force through its own elastic deformation and then gradually convert the elastic force into thrust, thereby preventing the sliding rod body 222 from being directly subjected to a large thrust and sliding out. Specifically, the elastic body 123 is made of silicone. Silicone has good deformation ability and can quickly recover after deformation, making it an excellent material for adjusting the elastic force.

[0034] like Figure 4 As shown, in the technical solution of this embodiment, the elastic body 123 is slidably disposed in the sleeve 122, and the end of the elastic body 123 away from the second elastic member 124 is fixedly connected to the sliding rod 222. This arrangement is equivalent to extending the sliding rod 222 through the elastic body 123 to connect with the second elastic member 124, thus avoiding the sense of frustration during elastic force transmission and improving the user experience of the sliding rod 222.

[0035] like Figure 4 As shown, in the technical solution of this embodiment, the diameter of the sliding rod body 222 near the elastic body 123 is smaller than the inner diameter of the sleeve 122 near the sliding rod body 222. This arrangement allows the sliding rod body 222 to enter the interior of the sleeve 122 to push the needle body 21 out to the maximum extent. It should be noted that the diameter of the limiting member 223 can be larger than the inner diameter of the sleeve 122. This arrangement limits the distance that the sliding rod body 222 can enter the interior of the sleeve 122, thereby avoiding severe squeezing of the second elastic member 124, which would cause the elastic member to fail. At the same time, when the sleeve 122 and the limiting member 223 collide with each other, the needle body at one end of the sliding rod body 222 can obtain a better thrust, so that the needle body 21 will not deviate during use, making the use of the needle body 21 more precise.
